Vancomycin-like drugs target peptidoglycan (PG) via binding to C-terminal d-Ala-d-Ala dipeptide. An engineered vancomycin has enhanced affinity for the PG stem peptide, due to probable interactions with a third residue, meso -diaminopimelic acid, in the PG. This engineered vancomycin displays enhanced killing of mycobacteria.
